Resolution
Width & Height
Controls the dimensions of the generated video in pixels.
| Setting | Range | Default |
|---|---|---|
| Width | 256-1280 | 512 |
| Height | 256-1280 | 320 |
Tips:
- Both dimensions should be divisible by 64 for best results
- Higher resolutions require more memory and time
- Start with smaller sizes for testing
Common Aspect Ratios
| Aspect | Width × Height | Use Case |
|---|---|---|
| 16:10 | 512×320, 640×400, 768×480 | Standard |
| 16:9 | 768×432, 1024×576 | Widescreen |
| 9:16 | 384×640, 432×768 | Portrait/Mobile |
| 1:1 | 512×512 | Social media |
| 2.4:1 | 768×320 | Cinematic |
Frames
Number of Frames
Total frames to generate. More frames = longer video.
| Setting | Range | Default |
|---|---|---|
| Frames | 9-121 | 25 |
Duration calculation:
Duration (seconds) = Frames ÷ FPS
Examples at 24 FPS:
- 25 frames = ~1 second
- 49 frames = ~2 seconds
- 73 frames = ~3 seconds
- 97 frames = ~4 seconds
FPS (Frames Per Second)
Playback speed of the generated video.
| Setting | Range | Default |
|---|---|---|
| FPS | 8-30 | 24 |
Tips:
- 24 FPS: Cinematic feel
- 30 FPS: Smooth motion
- 12-15 FPS: Animation style
Quality Settings
Inference Steps
Number of denoising steps. More steps = higher quality but slower.
| Setting | Range | Default |
|---|---|---|
| Steps | 10-100 | 40 |
Recommendations:
- 20-25: Fast preview
- 35-45: Good quality
- 50+: Maximum quality
The quality improvement diminishes after ~50 steps.
Guidance Scale
How closely the model follows your prompt.
| Setting | Range | Default |
|---|---|---|
| Guidance | 1.0-20.0 | 7.5 |
Effects:
- Low (1-3): More creative, may ignore prompt details
- Medium (5-8): Balanced adherence
- High (10+): Strict prompt following, may reduce quality
Recommended range: 5.0 - 10.0
Seed
Random Seed
Controls the randomness of generation.
| Setting | Range | Default |
|---|---|---|
| Seed | 0-2147483647 | Random |
Usage:
- Same seed + same parameters = identical output
- Leave at -1 for random seed each time
- Save the seed of good results to reproduce them
- Try seeds ±1 from good results for variations
Prompts
Main Prompt
Describe what you want to see in the video.
Best practices:
- Be descriptive and specific
- Include camera movement if desired
- Describe motion and action
- Mention lighting and atmosphere
Negative Prompt
Describe what you want to avoid.
Common negative prompts:
worst quality, low quality, blurry,
jittery motion, distorted,
watermark, text, logo,
static, still image
